"The chapter on structural geology provides guidance for site investigations of open pits, and for analyzing and presenting structural information for pit slope design. Methods of gathering and evaluating geological data are given first, followed by a description of work requirements during mine operations. Time requirements and costs are given to assist planning of the various activities during mine development. The objective of an engineering geological site investigation is to delineate design sectors for which orientations of slope faces, rock types and discontinuities are similar. This judgement is made on the basis of a semiquantitative rock strength description, and properties of geological discontinuities. All observations are presented by their averages and dispersions to enable a stability analysis to be made on the basis of probability"--Summary. Slopes (Soil mechanics) Strip mining Herget, G.
